These are definitely steps in the right direction. Google's AdWords platform continues to get better and better.

One thing I'd really like to see is PPA campaigns for smaller companies looking to become bigger companies :) Currently Google's PPA campaigns are reserved for ads generating over 300 conversions per month.

That leaves many companies out of the loop. Many companies that could tie ad budgets directly to performance (i.e. generation of revenue) could explode their ad budgets as returns continued to increase.

To me it seems like a win/win, where the more sales generated from PPA campaigns, the more money can be invested in larger PPA campaigns/payouts, resulting in more conversions, higher payouts, etc.

If someone could explain why Google wouldn't want smaller companies to be able use the services in this space, I'd certainly love to hear it!!
